ISO Price based on 2 pages Not for Resale ted without license from IHS FOREWORD ISO (the International Organization for Standardization) is a worldwide federation of national standards institutes (IsO Member Bodies). The work of devetoping International Standards is carried out through isO Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental and non-governmental, in liaison with isO, also take part in the work. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 1965 was drawn up by Technical Committee ISO/TC 20, Aircraft and space vehicles. It was approved in May 1970 by the Member Bodies of the following countries : Greece Australia South Africa, Rep. of Belgium India Spain Brazil Israel Switzerland Canada Italy Turkey Czechoslovakia Japan United Kingdom Egypt, Arab Rep. of Netherlands U.S.S.R.
